Abstract: Focusing on the flight test difficulty of fuel cell unmanned aerial vehicle (UAV) power system and aimed at improving the design and development level of power system, this paper designs and builds a hardware-in-the-loop (HIL) simulation platform of fuel cell UAV power system, on which the power system composed of fuel cell, lithium cell, DC/DC power converter, electronic governor and brushless motor is taken as the hardware, the mathematical models of UAV, autopilot, propeller and flight environment are taken as the software part, the throttle signal control of UAV and the load of motor in flight are taken as the simulation part, and the signal generator, dynamometer and torque loading device are taken as software and hardware interfaces. Facing the typical mission profiles and based on the state machine management strategy, the paper conducts a HIL simulation for power system of fuel cell/battery electric UAV, and analyzes the effectiveness and practicability of the HIL simulation platform and management strategy.

Key words: fuel cell, unmanned aerial vehicle (UAV), power system, hardware-in-the-loop (HIL) simulation, energy management
